This semester I am working with a fellow research student to develop some workflows to automate some analyses for my bioinformatics professor. This week I have been evaluating a scientific workflow solution called Taverna. I have been learning the basics from a powerpoint presentation here.
Taverna allows the user to construct workflows from pre-existing modules that do everything from retrieving sequences in genbank to aligning, analyzing and displaying the data in graph form. This is definitely a fully featured workflow solution. Workflows can be configured to be fail-safe, meaning I can specify alternate modules if 1 is not presently available. Also, when specifying more than 1 input, for example 4 gene sequences instead of 1, Taverna will automatically iterate over each input.
Our next task will be to discover if our workflow problem can be solved by configuring Taverna workflow with modules that already exist. I would actually like to use the API to create my own modules. Also, we need to investigate how easy it is take advantage of multiple processors and machines.
